Molybdenum ntawvyog ib daim ntawv nyias ua los ntawm molybdenum, uas tuaj yeem ua rau cov nplooj ntawv sib txawv thiab ntau thiab tsawg los ntawm kev txiav, txiav lossis stamping. Molybdenum yog cov khoom siv hlau nrog cov cim tshuaj Mo thiab atomic naj npawb 42. Nws yog cov hlau uas muaj cov ntsiab lus melting siab, siab zog, thiab siab corrosion kuj, thiab feem ntau yog siv rau hauv kev tsim cov khoom lag luam nrog kev kub siab, kev kub siab, thiab siab zog. Molybdenum phaj feem ntau yog siv rau hauv cov khoom siv hluav taws xob, hluav taws xob hluav taws xob, hlau, aerospace, thiab lwm yam. Nws muaj cov txiaj ntsig tseem ceeb hauv cov teb no vim nws qhov kub-kub oxidation tsis kam, siab hardness, thiab zoo hluav taws xob conductivity.

3. Cov txheej txheem tsim khoom
Cov txheej txheem tsim cov ntawv molybdenum feem ntau suav nrog cov kauj ruam hauv qab no:
- Kev npaj cov khoom raw: xaiv high-purity molybdenum blocks los yog molybdenum hmoov ua raw cov ntaub ntawv, thiab ces ua billets los ntawm kev sib tov, siab molding, thiab lwm yam txheej txheem.
- Sintering: muab lub billet tso rau hauv qhov kub kub sintering rauv, thiab sinter nws nyob rau hauv ib tug ntshiab hydrogen los yog nitrogen cua los tsim ib tug ntom molybdenum phaj.
- Kev kho cua txias: Muab sintered molybdenum phaj rau hauv dej kom txias ceev kom txhim kho qhov tawv thiab corrosion tsis kam ntawm molybdenum phaj.
- Kub dov: lub txias molybdenum phaj yog kub dov los ntawm kub dov zeb kom maj mam txo cov thickness ntawm molybdenum phaj thiab ncab nws mus rau hauv ib tug nyias phaj ntawm qhov yuav tsum tau loj.
- Kev Kho Kom Zoo: Cov kub dov molybdenum phaj yog raug rau kev ua haujlwm zoo xws li txiav, xuas nrig ntaus, khoov, stamping, thiab lwm yam.
Cov saum toj no yog cov txheej txheem ntau lawm ntawm molybdenum phaj, thiab cov txheej txheem tsim khoom tshwj xeeb yuav txawv nyob ntawm cov chaw tsim khoom thiab cov khoom xav tau.
4. Daim ntawv thov Yield
Molybdenum phaj feem ntau yog siv rau hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob electrothermal, thiab aerospace nyob rau hauv high-temperature thiab high-pressure ib puag ncig.
